Allow more blocks to be attached to animated blocksters

When placing a motor or hinge on an animated blockster, the animated blockster gets stuck in the sitting animation and cant move. I would like to be able to attach these certain blocks on one without it sitting down. Like how you can with the regular blocksters.

Start by locating the animated blockster attachment and sitting-animation entry points. Reproduce attaching a motor or hinge and compare it with the regular blockster behavior. Done means those blocks can attach without forcing the animated blockster into a stuck sitting animation.
